Abstract

In most cases, acute mitral valve regurgitation in the setting of infective endocarditis is caused by the destruction of either the mitral valve leaflets or the chordal apparatus. A 54-year-old woman had development of respiratory failure due to pulmonary oedema from severe acute mitral valve regurgitation in the setting of acute bacterial endocarditis. She was found to have a ruptured anterolateral papillary muscle from occlusion of the circumflex artery by embolic vegetations arising from the aortic valve. Although this occurrence is uncommon, an embolic phenomenon resulting in myocardial infarction and subsequent rupture of papillary muscle must be considered as a cause of acute severe mitral valve regurgitation.
